VEHICULAR VAPOR COMPRESSION TYPE REFRIGERATING CYCLE

摘要

PROBLEM TO BE SOLVED: To sufficiently improve drivability in a vehicle equipped with an air conditioner having a compressor obtaining motive power from an engine. SOLUTION: A first threshold valueθfor turning off an electromagnetic clutch is changed along a steady throttle opening curve L0 and a motive power cut line L1 having an almost similar shape according to a vehicle speed. Thus, the drivability can be sufficiently improved. The steady throttle opening curve L0 indicates the relationship between the vehicle speed when traveling on a flat road and throttle opening (an engine load) in a clam state.
